Grain Up — the questions people ask

How do I use a Grain Up promo code?
Pick a code below and click it — we copy it for you and send you to Grain Up. Paste it into the promo box at checkout before you pay.
Are these Grain Up codes tested?
Every code on this page is checked by hand before it goes live, and the ones that stop working are pulled.
What if none of the codes work?
Try a deal instead — those need no code at all. Codes are ordered by how well they are working right now, so start at the top.
How often is this page updated?
Daily. New Grain Up codes go up as soon as we can test them, and expired ones come down.
